摘要: 以磷酸三乙酯、硝酸铝和正硅酸乙酯为原料,通过它们的水解制备了Al·5·100SiO=0.25~3)凝胶.在600℃对凝胶进行热处理,使其中的有机基团炭化,从而制备出了镶嵌有碳纳米颗粒的xAl··100SiO=0.25,0.5)凝胶玻璃.在室温下以532nm激光(Nd:YAG)激发,在 630nm处有一强的发光峰,该发光现象是由镶嵌在凝胶玻璃中的纳米碳颗粒产生的.

Abstract: C-nanoparticles embedded xAl2O3· xP2O5·100SiO2 (x=0.25 or 0.5) gel-glasses were prepared by a sol-gel process. The gels synthesized through hydrolysis of PO(OC2H5)3, Al(NO3)3· 9H2O and Si(OC2H5)4, were heated at 600℃ for 10h, in which -- OC2H5 were carbonized to precipitate nanosized C particles. Glasses doped with C nanoparticles showed a strong roomtemperature photoluminescence with a peak at 630nm under 532nm Nd:YAG laser excitation. The photoluminescence spectra were caused by C nanoparticles embedded gel-glasses.

Key words: sol-gel process, C/xAl2O3·xP2O3·100SiO2 (, C-nanoparticles, photoluminescence properties
